After I got my stereo installed I noticed a loud electrical whine it sounds like a Jet Engine turning on about to blast off. Could it be the lame audio power wires that connect to the battery?

sound like you have the alternator whine or "engine noise"
what kind of system do you have (amps?)

common problem caused by a bad groung or running your rca next to your power wires

Here is my system 400w 2 channel for sub. 250w 4 channel for the interior speaks and a pioneer deck. The power wires look pretty cheap.

Make sure you ground wires are as short as possible and are touching the actual metal structure of the car (sand off any paint, etc). Also be sure you aren't running the RCA's and the power wires on the same side of the car.

if you're using "lame" power wires like you say, are you using "lame" rca's as well? if you are using a cheap amp kit, your rca's will not have proper electrical shielding, and you will most definitely pick up engine noise through them, even if you can power and rca on separate sides. check into that.

Yeah, I even added two of those Ground Loop Isolator's from Schoshe to try to fix the whine...that got rid of about half of the noise, but it's still annoying! I'll check the ground wires and the RCA and Power wires...are there any other fixes??

Properly installed amps will require zero ground loop isolators. The isolators are a band-aid and NOT a solution.

You should concentrate on finding and fixing the problem permanently rather than putting a band-aid on it.

Did you have the stereo installed by a shop? If so, YOU shouldn't be looking for anything.....the shop should fix it.

If not, you should start by reconnecting the ground to a better location making sure of a better connection. If that doesn't resolve the problem, you should check the power side of the amps. Do you have distribution block for both power and ground? If not, WHY the heck not and how are you getting power/ground to both amps? Is the connection good? Are you using proper gauge wire? If that's not it, move on to the input side. Are the RCA's good? Are they properly ran thru the vehicle? If that's not it, look at the equipment side. Is the HU new? Are the amps new? How high are the gains turned up?

If I had to guess based on the very small amount of info you've given so far, I'd bet that the problem lies in the installation side of the equation. I've seen cheap wires that when properly installed picked up zero noise, and I've seen good wires incorrectly installed that sound like your plane noise.

I did the speakers my friend did the HU and the shop did the two amps. I'm going to take it into the shop.

Thanks

Try putting power and remote wire on one side of the car, and then the speaker and rca wires on the other side.

sound like the rca cable were ran next to your power cables. try separating them on different sides of the car.

probably bad ground, crappy wires, my buddy has a similar system to mine in his crown vic and he used street wires, he gets the noise whenever he accelerates and the cd is changing tracks, i used a fosgate kit from best buy, i get it half off, and the thing sounds great

just need dyno mat or dynoxorb to fix the rattling

Update

Dude at the shop threw on a RCA filter and now the sound is gone. He ripped electrical tape off of two connecting RCA cables and threw on the filter. Whatever it worked.

I was gonna say, I doubt you got enough power to make the alternator whine. A lot of us including myself have more then double that rms w/o any issues.

Wait, why are you using RCA's that are too short? Do you realize that anytime you put in a "filter" of any kind you are degrading the signal even more. If that is truly your problem, a proper length RCA would do the same thing w/o the loss of using a filter.

What kind of "shop" tries to "fix" a problem with a filter instead of proper installation????? Honestly, I would stay far far away from a shop that put a band-aid on my open wound. If you're happy with it, cool. Personally, I would use the proper length RCA's and see if that eliminates the problem w/o any filters. In-line filters are not good for sound at all.

98 out of 100 times you have a bad ground. That filter is a bandaid to the system. Take it back, hand the stupid installer the filter and tell him to fix the real problem. I bet he didn't even scratch the paint off the body where he grounded the amp.
